99-kdump.conf: Omit nouveau and amdgpu module
Resolves: https://issues.redhat.com/browse/RHEL-52304
The GPU module provides no significant utility in second kernel, and it
introduces firmware that occupies lots of memory, which is critical in
the constrained environment of kdump. Omit it helps reduce memory usage
and optimize the crash recovery process.

Conflict: Yes, kexec-tools is split into 3 parts upstream, some changes should
be applied to kdump-utils Makefile, but RHEL-9 kexec-tools doesn't have that.
Also missing upstream commits:
- 1732a3b(mkdumprd: Omit rdma module)
- 7fec2f56(mkdumprd: simplify handling of dracut arguments)

Add kdump dracut config
In some cases, customizing the first kernel's initrd is necessary by
modifying the dracut `omit_dracutmodules` options, such as in Bootc
or CoreOS scenarios [1]. However, these changes can unintentionally
break existing functionality in kdump. For instance, setting
`omit_dracutmodules='nfs'` prevents the `nfs` module from being added.
Additionally, some dracut configurations [2] use
`dracutmodules+='some modules'` instead of
`add_dracutmodules+='some modules'`. When `dracutmodules` is non-empty,
dracut includes only the specified modules, which can result in an
initrd that lacks necessary modules, causing kdump to fail.
Dracut upstream support --add-confdir now, kdump can use this
option when building kdump initramfs.
This patch moved the hardcoded dracutmodules from mkdumprd to the new
conf file /lib/kdump/dracut.conf.d/99-kdump.conf, it is easier to check
and modify to omit or add certain modules. This patch also initialize
dracutmodules to empty to avoid the influence of other configurations.
